Nuns’ Expiation (Pācittiya) 49

Bi-Pc.49.1.1BD.3.337 … at Sāvatthī in the Jeta Grove in Anāthapiṇḍika’s monastery. Now at that time the group of six nuns learnt worldly knowledge.[1] People … spread it about, saying: “How can these nuns learn worldly knowledge, like women householders who enjoy pleasures of the senses?” Nuns heard these people who … spread it about. Those who were modest nuns … spread it about, saying: “How can this group of six nuns learn worldly knowledge?” …

“Is it true, as is said, monks, that the group of six nuns learn worldly knowledge?”

“It is true, lord.”

The enlightened one, the lord, rebuked them saying:

“How, monks, can this group of six nuns learn worldly knowledge? It is not, monks, for pleasing those who are not (yet) pleased … this rule of training:

“Whatever nun should learn worldly knowledge, there is an offence of expiation.”

Footnotes and references:

tiracchāna-vijjā, literally “animal wisdom.” B.C. Law, History of Pali Literature 1. p.75 has “art for her livelihood,” but Old Commentary, does not bear this out. At Vin.2.139 it is a dukkaṭa for a monk to learn this. Cf.tiracchānakathā at Monks’ Bu-Pc.85, “worldly talk”—i.e., talk on matters concerning life in the world. Vinaya Texts iii.152 renders by “the low arts”—those set out at DN.i.9–DN.i.12.

parittā. Cf.DN.iii.206, where monks are enjoined to learn and master the Āṭānāṭiya rakkhā or ward rune. This is called atthasaṃhitā, connected with the goal; cf. foregoing definition of “worldly knowledge,” which therefore looks as if it does not include protective spells. See Dialogues of the Buddha 3.185ff. for discussion of position and use of the various named parittās in early Buddhism. The proximity of writing (late?) and protective spells (early?) points to a patchwork compilation of this Pācittiya.
